Amber Bottles Polystop
A laboratory glass amber bottle is a specialized container commonly used in laboratories to store and protect light-sensitive substances, chemicals, or solutions. These bottles are made from amber-colored glass, which provides protection against ultraviolet (UV) and visible light radiation. The amber glass helps to minimize the degradation and decomposition of light-sensitive contents by blocking a significant portion of the light spectrum.
The amber color of the glass is achieved by adding iron, sulfur, and other compounds during the glass manufacturing process. This coloration is what gives the bottles their distinctive amber or brown appearance.
Laboratory glass amber bottles typically come in various sizes, ranging from small volumes of a few milliliters to large capacities of several liters. They often have a screw-on or snap-on cap, providing a secure and airtight seal to prevent spills, evaporation, and contamination.
Due to their ability to protect light-sensitive substances, laboratory glass amber bottles are widely used in chemistry, biology, pharmaceuticals, and other scientific fields where sample integrity and stability are crucial.
Balance lever
The best definition of a balance lever is a simple machine that consists of a rigid bar or beam that pivots around a fixed point called the fulcrum. It is used to compare the weights or forces of two objects and determine if they are in equilibrium (balanced) or if one side is heavier than the other (unbalanced).
The balance lever operates on the principle of torque, where the torque (rotational force) exerted on one side of the fulcrum is equal to the torque on the other side when the system is in equilibrium. This principle is expressed by the formula: Torque = Force × Distance from fulcrum.
By placing known masses or weights on one side of the lever and an unknown weight on the other side, the balance lever can be used as a weighing scale. When the lever is in balance, the two sides are equal in weight or force. This concept has been widely used in various applications, from traditional weighing scales to more complex systems like seesaws or construction equipment.
blow pipes
A blowpipe apparatus is a scientific instrument used in analytical chemistry and mineralogy for conducting various tests, particularly flame tests and microchemical reactions. It typically consists of a small tube or pipette through which a controlled stream of air or oxygen is blown onto a sample being heated. This stream of air or oxygen enhances the combustion of the sample, allowing the observation of characteristic colors emitted by different elements when they are vaporized and excited by the heat. The blowpipe apparatus is often used to identify and differentiate between different elements and compounds based on their unique emission spectra and reactions.
